Worth the Blood, Sweat, and Tears?

Joshua Smith (@kognate) is a Lead Mobile Developer at iRx Reminder, frequent Cocoa Conference speaker and author of an upcoming book with O’Reilly on core data. We recently sat down to talk about core data and its complexities.

Admittedly, the idea of Ballmer, Cook and Schmidt all battling it out Highlander-style is appealing...

As long as most people can remember, the smartphone space has been a contested one. Before the iPhone became temporarily ubiquitous, RIM and Palm were fighting it out to own the market, and today you have a plethora of platforms to choose from, including Android, iOS, Windows, and Blackberry. And because many mobile OS vendors license their products to third-party manufacturers, some mobile operating systems have little market share wars of their own, such as HTC fighting it out with Samsung and Motorola for the Android customer base.

I’ve talked before, in the context of languages, about the damage that the paradox of choice can bring to societies. Having more product choices may not make us any happier, or even lead to better products, but only create the vague uncertainty that whichever product choice we make, it wasn’t the correct one.

For obvious reasons, a monopoly doesn’t usually work out that well either, at least in mature markets with stable standards. Very few will argue that Microsoft’s most innovative years occurred during the period that they sat “fat, dumb and happy” with 90%+ desktop market share. But I would argue that there comes a time when some choices should be left to die a dignified death, and that both Windows and Blackberry mobile products are at that point.Read more…

Scarfolk Council — clever satire, the concept being a UK town stuck in 1979. Tupperware urns, “put old people down at birth”. The 1979 look is gorgeous. (via BoingBoing)

Stop Designing Fragile Web APIs — It is possible to design your API in a manner that reduces its fragility and increases its resilience to change. The key is to design your API around its intent. In the SOA world, this is also referred to as business-orientation.

@life100yearsago (Twitter) — account that tweets out fragments of New Zealand journals and newspapers and similar historic documents, as part of celebrating the surprising and the commonplace during WWI. My favourite so far: “Wizard” stones aeroplane. (via NDF)

An interview with John Anderson

In this interview, the author of Appcelerator Titanium: Up and Running describes how Titanium can be used to generate native mobile apps from JavaScript code. He distinguishes the Titanium platform from native API programming and from other popular JavaScript platforms for mobile devices. We look at the way Titanium exploits the expressiveness and flexibility of JavaScript, and some of the directions that the Appcelerator company is taking Titanium.Read more…

If Jenkins is good enough for Apple to use, why not give it a try yourself?

One of the pleasant surprises I learned last year at WWDC is that Apple uses Jenkins to automate their iOS app builds. Since we were already using Jenkins to do the same thing at the Day Job, it was a nice confirmation that we had taken the right approach.

However, until recently, getting Jenkins to fire off an Xcode build, bundle it into an IPA, and sign it correctly was a real pain. Thankfully, in 2012, a Jenkins plugin for Xcode integration was released. It can be installed directly from the Jenkins plugin management page, and once installed, gives you a new build step called Xcode that you can add to a build.

MLDemos — an open-source visualization tool for machine learning algorithms created to help studying and understanding how several algorithms function and how their parameters affect and modify the results in problems of classification, regression, clustering, dimensionality reduction, dynamical systems and reward maximization.

Industrial Internet — the O’Reilly report on the industrial Internet of things is out. Prasad suggests an illustration: for every car with a rain sensor today, there are more than 10 that don’t have one. Instead of an optical sensor that turns on windshield wipers when it sees water, imagine the human in the car as a sensor — probably somewhat more discerning than the optical sensor in knowing what wiper setting is appropriate. A car could broadcast its wiper setting, along with its location, to the cloud. “Now you’ve got what you might call a rain API — two machines talking, mediated by a human being,” says Prasad. It could alert other cars to the presence of rain, perhaps switching on headlights automatically or changing the assumptions that nearby cars make about road traction.

Unique in the Crowd: The Privacy Bounds of Human Mobility (PDF, Nature) — We study fifteen months of human mobility data for one and a half million individuals and find that human mobility traces are highly unique. In fact, in a dataset where the location of an individual is specified hourly, and with a spatial resolution equal to that given by the carrier’s antennas, four spatio-temporal points are enough to uniquely identify 95% of the individuals. We coarsen the data spatially and temporally to find a formula for the uniqueness of human mobility traces given their resolution and the available outside information. This formula shows that the uniqueness of mobility traces decays approximately as the 1/10 power of their resolution. Hence, even coarse datasets provide little anonymity. These findings represent fundamental constraints to an individual’s privacy and have important implications for the design of frameworks and institutions dedicated to protect the privacy of individuals. As Edd observed, “You are a unique snowflake, after all.” (via Alasdair Allan)

Military Open Source, State of Internet, Visualizing Budgets, and Hacking Your iDevice

Mil-OSS 4 — 4th military open source software working group conference, in Rosslyn VA. Oct 15-17. Tutorials and sessions will cover: Linux, Geospatial, LiDAR, Drupal, cloud, OSS policy and law, Android and many other topics. The last day will have a 1/2 day unconference for up-and-coming issues.

State of Internet Slides (Business Insider) — Apple could buy Disney using cash at hand. Boggle. This presentation has plenty of numbers for those who like them.

libimobiledevice — LGPLed open source library which talks the protocols to support iPhone®, iPod Touch®, iPad® and Apple TV® devices. Unlike other projects, it does not depend on using any existing proprietary libraries and does not require jailbreaking. It allows other software to easily access the device’s filesystem, retrieve information about the device and it’s internals, backup/restore the device, manage SpringBoard® icons, manage installed applications, retrieve addressbook/calendars/notes and bookmarks and (using libgpod) synchronize music and video to the device. Runs on Linux, OS X, and Windows.
